| Factors Affecting Performance [Text Block] | Management’s discussion of Fund performance Performance highlights Delaware Ivy Multi-Asset Income Fund (Class A) returned 17.33% (excluding sales charge) for the 12 months ended September 30, 2024. The Delaware Ivy Multi-Asset Income Fund is a real assets portfolio that aims to provide capital appreciation and income, inflation protection, and diversification with a dynamic, multi-asset allocation framework built on market assessments using pairwise views by an experienced multi-asset allocation team with specialized experts in each asset class. During the period, the asset classes in scope for the Fund that delivered the highest returns were: Global equities Global listed infrastructure Global real estate The asset classes in scope for the Fund with the lowest returns during the period were: Global natural resources Investment grade fixed income High yield fixed income The largest detractor from performance relative to the blended benchmark of the Fund was an underweight to global equities combined with a negative selection effect within global equities primarily due to the extremely strong performance from US equities, particularly within the growth style cohort and mega-cap technology stocks. Additional detractors to relative performance included the These headwinds were partially offset by the positive effects of overweight allocations to global real estate and global listed infrastructure, which provided very strong returns more in-line with global equities during the period. *The blended benchmark is computed using a combination of 50% MSCI ACWI Index (net) / 50% ICE BofA US High Yield Index. |

| Factors Affecting Performance [Text Block] | Management’s discussion of Fund performance Performance highlights Delaware Ivy Multi-Asset Income Fund (Class Y) returned 17.32% (excluding sales charge) for the 12 months ended September 30, 2024. The Delaware Ivy Multi-Asset Income Fund is a real assets portfolio that aims to provide capital appreciation and income, inflation protection, and diversification with a dynamic, multi-asset allocation framework built on market assessments using pairwise views by an experienced multi-asset allocation team with specialized experts in each asset class. During the period, the asset classes in scope for the Fund that delivered the highest returns were: Global equities Global listed infrastructure Global real estate The asset classes in scope for the Fund with the lowest returns during the period were: Global natural resources Investment grade fixed income High yield fixed income The largest detractor from performance relative to the blended benchmark of the Fund was an underweight to global equities combined with a negative selection effect within global equities primarily due to the extremely strong performance from US equities, particularly within the growth style cohort and mega-cap technology stocks. Additional detractors to relative performance included the These headwinds were partially offset by the positive effects of overweight allocations to global real estate and global listed infrastructure, which provided very strong returns more in-line with global equities during the period. *The blended benchmark is computed using a combination of 50% MSCI ACWI Index (net) / 50% ICE BofA US High Yield Index. |
