Fixing Filament Admin Sidebar Header Positioning

The Issue

The Filament admin panel's sidebar header was not behaving as expected on desktop screens. Specifically, its positioning wasn't sticky, leading to a poor user experience when scrolling through long lists of navigation items.

The Fix

A CSS update was implemented to ensure the sidebar header remains fixed at the top of the screen on desktop viewports. This leverages position: sticky along with top: 0 to keep the header visible during scrolling.

/* Fix sidebar header sticky positioning on desktop */
@media (min-width: 1024px) {
    .fi-sidebar-header {
        position: sticky !important;
        top: 0 !important;
        z-index: 10;
    }
}

Technical Details

• position: sticky: This CSS property allows an element to behave as relatively positioned until it crosses a specified threshold, at which point it becomes fixed.
• top: 0: Sets the sticky element to adhere to the top of its containing element.
• z-index: 10: Ensures the header stays above other elements on the page.
• !important: While generally discouraged, it was used to override existing styles and ensure the sticky positioning takes effect.

Impact

This change improves the usability of the Filament admin panel on desktop devices by ensuring the sidebar header is always visible, providing quick access to navigation elements.
