| Expenses [Text Block] | WHAT WERE THE FUND COSTS FOR THE LAST YEAR? (based on a hypothetical $10,000 investment) Class Name Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment * Class A $108 1.00% | [1] |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended December 31, 2024, Class A shares of ClearBridge Dividend Strategy Fund returned 16.68%. The Fund compares its performance to the S&P 500 Index, which returned 25.02% for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Broadcom, a semiconductor developer and manufacturer, shares rose on positive sentiment for artificial intelligence (AI) semiconductor demand and the expanding market for its AI-specific chips. ↑ Apollo Global Management, an American private equity firm, performed well as lower interest rates offered a catalyst for private equity broadly, where credit and real estate portfolios stand to benefit. The U.S. presidential election in November 2024 also raised the prospect of lower taxes and less regulation, bolstering hopes for continued positive economic momentum, increased M&A activity and greater corporate profits. ↑ Williams Companies, an energy company, shares rose on strong financial results, with several growth projects set to come online, and improved natural gas price outlook and growing acknowledgment that midstream infrastructure plays a key role to back-up renewable power as AI demand increases. Top detractors from performance: ↓ Intel, a technology company, results and profitability outlook continued to disappoint, sending shares lower. With its turnaround taking longer than anticipated and the suspension of its dividend, the Fund exited the position. ↓ Nestle, a food and drink company, cut its full-year outlook amid weaker consumer demand and the actions it was taking to reduce customer inventories. ↓ Comcast, a telecommunications company, shares were lower amid a tough broadband competitive landscape that could see fewer net adds due to seasonality and the impact of the Affordable Connectivity Program, which could pressure revenues. | |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended December 31, 2024, Class IS shares of ClearBridge Dividend Strategy Fund returned 17.09%. The Fund compares its performance to the S&P 500 Index, which returned 25.02% for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Broadcom, a semiconductor developer and manufacturer, shares rose on positive sentiment for artificial intelligence (AI) semiconductor demand and the expanding market for its AI-specific chips. ↑ Apollo Global Management, an American private equity firm, performed well as lower interest rates offered a catalyst for private equity broadly, where credit and real estate portfolios stand to benefit. The U.S. presidential election in November 2024 also raised the prospect of lower taxes and less regulation, bolstering hopes for continued positive economic momentum, increased M&A activity and greater corporate profits. ↑ Williams Companies, an energy company, shares rose on strong financial results, with several growth projects set to come online, and improved natural gas price outlook and growing acknowledgment that midstream infrastructure plays a key role to back-up renewable power as AI demand increases. Top detractors from performance: ↓ Intel, a technology company, results and profitability outlook continued to disappoint, sending shares lower. With its turnaround taking longer than anticipated and the suspension of its dividend, the Fund exited the position. ↓ Nestle, a food and drink company, cut its full-year outlook amid weaker consumer demand and the actions it was taking to reduce customer inventories. ↓ Comcast, a telecommunications company, shares were lower amid a tough broadband competitive landscape that could see fewer net adds due to seasonality and the impact of the Affordable Connectivity Program, which could pressure revenues. | |
