| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 6.80%, reflecting performance at the net asset value (NAV) of Class A shares with all distributions reinvested, compared to a securities market index with investment characteristics similar to those of the Fund, the ICE BofA Green Bond Index (USD Hedged), which returned 7.81% over the same period. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 7.02%, reflecting performance at the net asset value (NAV) of Class F3 shares with all distributions reinvested, compared to a securities market index with investment characteristics similar to those of the Fund, the ICE BofA Green Bond Index (USD Hedged), which returned 7.81% over the same period. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 6.48%, reflecting performance at the net asset value (NAV) of Class R3 shares with all distributions reinvested, compared to a securities market index with investment characteristics similar to those of the Fund, the ICE BofA Green Bond Index (USD Hedged), which returned 7.81% over the same period. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 7.02%, reflecting performance at the net asset value (NAV) of Class R6 shares with all distributions reinvested, compared to a securities market index with investment characteristics similar to those of the Fund, the ICE BofA Green Bond Index (USD Hedged), which returned 7.81% over the same period. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment.

Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, global equity markets delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 11.30%, reflecting performance at the net asset value (NAV) of Class R6 shares, compared to the 6.27% of a securities market index with investment characteristics similar to those of the Fund, the MSCI Emerging Markets Index (Net). The Fund's broad-based market index, the MSCI EAFE Index (Net), returned 11.21% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, global equity markets delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 9.06%, reflecting performance at the net asset value (NAV) of Class F shares with all distributions reinvested, compared to a securities market index with investment characteristics similar to those of the Fund, the Bloomberg U.S. Floating Rate Notes Index, which returned 6.71% over the same period. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 9.13%, reflecting performance at the net asset value (NAV) of Class R6 shares with all distributions reinvested, compared to a securities market index with investment characteristics similar to those of the Fund, the Bloomberg U.S. Floating Rate Notes Index, which returned 6.71% over the same period. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 12.77%, reflecting performance at the net asset value (NAV) of Class F3 shares, compared to the 7.69% of a securities market index with investment characteristics similar to those of the Fund, the MSCI All Country World ex USA Growth Index (Net). The Fund's broad-based market index, the MSCI EAFE Index (Net), returned 11.21% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, global equity markets delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 12.37%, reflecting performance at the net asset value (NAV) of Class R4 shares, compared to the 7.69% of a securities market index with investment characteristics similar to those of the Fund, the MSCI All Country World ex USA Growth Index (Net). The Fund's broad-based market index, the MSCI EAFE Index (Net), returned 11.21% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, global equity markets delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 11.41%, reflecting performance at the net asset value (NAV) of Class A shares, compared to the 9.95% of a securities market index with investment characteristics similar to those of the Fund, the ICE BofA High Yield U.S. Corporate Cash Pay BB-B (1-5yrs) Index. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, U.S. high yield credit delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 11.08%, reflecting performance at the net asset value (NAV) of Class R3 shares, compared to the 9.95% of a securities market index with investment characteristics similar to those of the Fund, the ICE BofA High Yield U.S. Corporate Cash Pay BB-B (1-5yrs) Index. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, U.S. high yield credit delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? For the fiscal year ended July 31, 2024, the Fund returned 11.63%, reflecting performance at the net asset value (NAV) of Class R5 shares, compared to the 9.95% of a securities market index with investment characteristics similar to those of the Fund, the ICE BofA High Yield U.S. Corporate Cash Pay BB-B (1-5yrs) Index. The Fund's broad-based market index, the Bloomberg Aggregate Bond Index, returned 5.10% over the same period. Positive factors for the markets included momentum around the soft-landing narrative, specifically in the second half of the period, which was supported by signs of a cooling labor market and a slowing economy, leading the market to adjust its expectations of future interest rate cuts by the U.S. Federal Reserve (the Fed). Negative factors, specifically in the beginning of the period, included stronger-than-expected GDP growth, resilient labor market data, and persistently high inflation readings that led to a more prolonged interest rate environment. Against this backdrop, U.S. high yield credit delivered strong returns. Top contributors to performance: Top detractors from performance: | ||||||
