The load filter dropdown was being cut off when the button was positioned
on the left side of the screen due to static right-0 alignment. This became
more problematic as the button position changes with window resize.
Changes:
- Added dynamic dropdown alignment calculation based on button position
and available viewport space
- Implemented smart positioning logic that checks available space on both
left and right sides before deciding alignment
- Added window resize listener using requestAnimationFrame to dynamically
update dropdown position while open
- Added data-load-filter-btn attribute for reliable DOM querying
- Changed from static right-0 to dynamic :class binding for left/right
alignment
Technical details:
- Alpine.js state: dropdownAlign tracks current alignment (left/right)
- calculateAlignment() method computes button position and available space
- Uses getBoundingClientRect() to measure button position relative to viewport
- Prefers side with >=320px space, otherwise chooses larger side
- requestAnimationFrame ensures smooth updates during resize without
performance degradation
Fixes issue where dropdown extends beyond viewport edge when button
is near left or right edge of screen.
