class Slack::BlockKit::Element::MultiStaticSelect

A select menu, just as with a standard HTML <select> tag, creates a drop down menu with a list of options for a user to choose. The select menu also includes type-ahead functionality, where a user can type a part or all of an option string to filter the list.

This is the simplest form of select menu, with a static list of options passed in when defining the element.
