| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class A shares of the Fund returned 39.09% (unadjusted for sales charges) for the period ended September 30, 2024. The Fund's broad-based index, the Russell 1000 ® ® Stock selection in the information technology sector was the primary reason for the Fund’s underperformance in the annual period. Synopsys, Inc. (1.8%), a provider of design tools to the semiconductor industry, lost ground due to a lack of positive earnings revisions, concerns about the potential impact of increased technology export restrictions, and challenges at one of its key customers. Five9, Inc. (0.2%), which lagged on worries that the growing use of artificial intelligence (AI) would dampen demand for its customer-contact software, also hurt results in the sector. On the plus side, the Fund benefited from an overweight in NVIDIA Corp. (10.4%) and an underweight in Apple, Inc. (9.2%). Selection in the healthcare sector detracted as well. Shares of Dexcom, Inc. (0.9%), a producer of continuous glucose monitoring systems, pulled back sharply in response to a severe guidance cut related to poor execution. The Fund was also hurt by its position in Agilon, Inc. (0.1%). The stock slid as higher cost pressures, caused by greater utilization rates from Medicare Advantage patients, led to weakness in its results and forward guidance. An underweight in Eli Lilly & Co. (1.1%), which continued to outperform behind optimism regarding its GLP-1 weight loss treatments, was an additional source of underperformance in the sector. On the other hand, Boston Scientific Corp. (1.2%) was a notable contributor. Outside of technology and healthcare, Estee Lauder Companies, Inc. (0.5%) and Lululemon Athletica, Inc. (0.4%) — both of which were hurt by slowing sales growth — were the largest detractors. On the positive side, the Fund strongly outperformed in the financials sector thanks to a position in the insurer Progressive Corp. (3.4%). The stock rallied as a favorable auto insurance environment translated to robust earnings growth. Holdings in Intercontinental Exchange, Inc. (1.2%) and American Express (0.6%) further helped results. The Fund also exhibited relative strength in communication services, highlighted by a position in Spotify Technology SA (1.2%). The company reported record profits and an increased number of users, and it announced a price increase for its premium service. Percentages in parentheses are based on the Fund’s net assets as of September 30, 2024. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class R6 shares of the Fund returned 39.53% for the period ended September 30, 2024. The Fund's broad-based index, the Russell 1000 ® ® Stock selection in the information technology sector was the primary reason for the Fund’s underperformance in the annual period. Synopsys, Inc. (1.8%), a provider of design tools to the semiconductor industry, lost ground due to a lack of positive earnings revisions, concerns about the potential impact of increased technology export restrictions, and challenges at one of its key customers. Five9, Inc. (0.2%), which lagged on worries that the growing use of artificial intelligence (AI) would dampen demand for its customer-contact software, also hurt results in the sector. On the plus side, the Fund benefited from an overweight in NVIDIA Corp. (10.4%) and an underweight in Apple, Inc. (9.2%). Selection in the healthcare sector detracted as well. Shares of Dexcom, Inc. (0.9%), a producer of continuous glucose monitoring systems, pulled back sharply in response to a severe guidance cut related to poor execution. The Fund was also hurt by its position in Agilon, Inc. (0.1%). The stock slid as higher cost pressures, caused by greater utilization rates from Medicare Advantage patients, led to weakness in its results and forward guidance. An underweight in Eli Lilly & Co. (1.1%), which continued to outperform behind optimism regarding its GLP-1 weight loss treatments, was an additional source of underperformance in the sector. On the other hand, Boston Scientific Corp. (1.2%) was a notable contributor. Outside of technology and healthcare, Estee Lauder Companies, Inc. (0.5%) and Lululemon Athletica, Inc. (0.4%) — both of which were hurt by slowing sales growth — were the largest detractors. On the positive side, the Fund strongly outperformed in the financials sector thanks to a position in the insurer Progressive Corp. (3.4%). The stock rallied as a favorable auto insurance environment translated to robust earnings growth. Holdings in Intercontinental Exchange, Inc. (1.2%) and American Express (0.6%) further helped results. The Fund also exhibited relative strength in communication services, highlighted by a position in Spotify Technology SA (1.2%). The company reported record profits and an increased number of users, and it announced a price increase for its premium service. Percentages in parentheses are based on the Fund’s net assets as of September 30, 2024. |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Class S shares of the Fund returned 39.43% for the period ended September 30, 2024. The Fund's broad-based index, the Russell 1000 ® ® Stock selection in the information technology sector was the primary reason for the Fund’s underperformance in the annual period. Synopsys, Inc. (1.8%), a provider of design tools to the semiconductor industry, lost ground due to a lack of positive earnings revisions, concerns about the potential impact of increased technology export restrictions, and challenges at one of its key customers. Five9, Inc. (0.2%), which lagged on worries that the growing use of artificial intelligence (AI) would dampen demand for its customer-contact software, also hurt results in the sector. On the plus side, the Fund benefited from an overweight in NVIDIA Corp. (10.4%) and an underweight in Apple, Inc. (9.2%). Selection in the healthcare sector detracted as well. Shares of Dexcom, Inc. (0.9%), a producer of continuous glucose monitoring systems, pulled back sharply in response to a severe guidance cut related to poor execution. The Fund was also hurt by its position in Agilon, Inc. (0.1%). The stock slid as higher cost pressures, caused by greater utilization rates from Medicare Advantage patients, led to weakness in its results and forward guidance. An underweight in Eli Lilly & Co. (1.1%), which continued to outperform behind optimism regarding its GLP-1 weight loss treatments, was an additional source of underperformance in the sector. On the other hand, Boston Scientific Corp. (1.2%) was a notable contributor. Outside of technology and healthcare, Estee Lauder Companies, Inc. (0.5%) and Lululemon Athletica, Inc. (0.4%) — both of which were hurt by slowing sales growth — were the largest detractors. On the positive side, the Fund strongly outperformed in the financials sector thanks to a position in the insurer Progressive Corp. (3.4%). The stock rallied as a favorable auto insurance environment translated to robust earnings growth. Holdings in Intercontinental Exchange, Inc. (1.2%) and American Express (0.6%) further helped results. The Fund also exhibited relative strength in communication services, highlighted by a position in Spotify Technology SA (1.2%). The company reported record profits and an increased number of users, and it announced a price increase for its premium service. Percentages in parentheses are based on the Fund’s net assets as of September 30, 2024. |
