🔍 Custom filter logic

By default this component uses a fuzzy search algorithm to filter options but also allows you to opt-out and use your custom logic if you want to below is the example doing just case insensitive search

export function filterOptions(options, filter) {
  if (!filter) {
    return options;
  }
  const re = new RegExp(filter, "i");
  return options.filter(({ value }) => value && value.match(re));
}

🌐 Internationalization

You can easily Internationalize this component by passing prop overrideStrings so that UI strings can be presented in a different language

default values for overrideStrings are as below

{
  "selectSomeItems": "Select...",
  "allItemsAreSelected": "All items are selected.",
  "selectAll": "Select All",
  "search": "Search",
  "clearSearch": "Clear Search"
}

🎛 Custom Value Renderer

Optionally customise value renderer view by passing valueRenderer prop

const customValueRenderer = (selected, _options) => {
  return selected.length
    ? selected.map(({ label }) => "✔️ " + label)
    : "😶 No Items Selected";
};

🎛 Custom Item Renderer

Optionally customise dropdown item by passing ItemRenderer prop

Default Item Renderer

💅 Themeing

You can override CSS variables to customize the appearance

.multi-select {
  --rmsc-main: #4285f4;
  --rmsc-hover: #f1f3f5;
  --rmsc-selected: #e2e6ea;
  --rmsc-border: #ccc;
  --rmsc-gray: #aaa;
  --rmsc-bg: #fff;
  --rmsc-p: 10px; /* Spacing */
  --rmsc-radius: 4px; /* Radius */
  --rmsc-h: 38px; /* Height */
}

use !important if CSS variables are not getting applied
