| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Congress Intermediate Bond ETF (CAFX) outperformed the Bloomberg U.S. Intermediate Government/Credit Total Return Index by seven basis points during the period of inception (09/09/24) to October 31, 2024 with a return of -1.40% compared with -1.47% for the index. During this limited period, the U.S. bond markets incurred weak performance as interest rates with maturities longer than six months rose substantially during this period. The US Treasury 2-year rate was up 0.58% and the US Treasury 10-year rate was up 0.64%. The recent movement higher in rates was primarily due to better-than expected economic releases—which lowered or delayed market expectations of future rate cuts by the Federal Reserve. The primary detractor for the Fund during this short period was the security selection within the Banks/ Financials sector and US Treasury debt exposure. The primary contributor during the period was the overallocation to the Industrials sector and the asset-backed securities exposure. |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Congress Large Cap Growth ETF underperformed the Russell 1000 growth index by 645 bps during the trailing 1 year period ended October 31, 2024 with a return of 36.55% vs. 43.77% for the index. During this period, U.S. equities emerged as the vanguard of global markets, buoyed by an air of investor optimism and a robust economic landscape. Our nation’s economy displayed remarkable resilience, marked by strong labor markets and easing inflation. The top contributors during the year were security selection with consumer staples, security selection within communication services, and security selection within industrials sector. The primary detractors to performance were security selection within information technology, security selection within financials, and asset allocation in healthcare. |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? On a one-year period ending October 31, 2024, the Congress SMid Growth ETF returned 27.78% vs. the Russell 2500 Growth benchmark of 34.21%. The market experienced some volatility in August as investors began to raise concerns on the high costs of developing AI. In addition, the Federal Reserve cut interest rate by 50 basis points spurred a rally that favored lower quality companies. The primary detractor during the period was security selection within Information Technology, primarily not holding Super Micro Computer (+242%) and holding DoubleVerify (-39%). On the other hand, stock selection within Industrial and Consumer Discretionary were positive contributors to the performance. The top individual active contributor was Comfort Systems which returned over 115% in the period. |
