Help for auto-size work area.

[sinesigiuseppe69-netizen]

Hi, can anyone help me? I created an application and is there a way to make the sidebar or vertical bar appear when the page is resized? I need this because I need to run the app on multiple PCs with different screens. I tried using containers, but it's really cumbersome. Thanks for your help.

✅ What works
Place your sidebar and content area as containers directly on the page and set their anchors:
Sidebar container → anchor: "Stretch-Height" (grows in height, fixed width)
Main content area → anchor: "Stretch-Both" (fills all remaining space)
The anchor property is what makes a container resize with the window. The scrollable property is unrelated — it only controls whether the internal content scrolls when it doesn't fit.
✅ If your main layout uses tabs
Place the tabwidget directly on the page with anchor: "Stretch-Both" — the tab will grow with the window. Inside each tab, use a single container as the main widget. The content inside will be accessible via native scroll.
❌ Known limitation: individual widgets inside tabs
EPD uses absolute positioning by design — that's what makes the visual canvas possible. The ResizeManager works at page level but cannot reposition individual widgets inside tabs. This is a fundamental tradeoff inherent to any visual canvas that uses absolute positioning.

It is also worth keeping in mind that EPD is designed for quickly building prototypes, utilities and small desktop tools. The whole point is to save time — you design the UI visually by dragging and dropping widgets, connect them with logic without writing boilerplate code, and compile to a standalone .exe without touching Python environments, pip dependencies or PyInstaller configuration. What would take hours of setup and manual coding in a conventional IDE can be done in minutes in EPD. It is not intended for building highly complex production applications with deeply nested resizable layouts. For straightforward tools and apps it works extremely well, and that is the sweet spot it is designed for.
