mdlivingston/mat-select-filter

The **mat‑select‑filter** library adds searchable, filterable dropdown functionality to Angular Material `<mat-select>` components, letting developers quickly turn standard selects into type‑ahead filters that can work with plain arrays, arrays of objects, and even grouped option sets. It’s aimed at Angular developers who use Material Design and want an easy‑to‑integrate, customizable filtering UI without building the logic themselves.
