To apply it to all dropdowns in your project, add this to your stylesheet.css
.ia_dropdown__optionsModal {
width: auto !important;
}
to apply it to specific dropdowns within your project add this to your stylesheet.css
.ia_dropdown__optionsModal:has(.psc-Dropdown-AutoSizeOptionsModal) {
width: auto !important;
}
then add Dropdown-AutoSizeOptionsModal to dropdownOptionsStyle.classes of the dropdown you wish to expand
