/* public/css/components/multiselect-filter.css
 *
 * The searchable multi-select in components/multiSelectFilter.js — used in the
 * Stock screen's filter panel to pick several titles, imprints or holders.
 *
 * Sits inside a .filter-group beside plain .filter-input / .filter-select
 * controls (components/enhanced-sales.css), so the toggle deliberately matches
 * their padding, border and font: a row of filters must read as one row of
 * filters even though one of them opens a panel.
