Create a wa-dropdown component — wa_dropdown • shiny.webawesome

Generated wrapper for the Web Awesome wa-dropdown component. When used as a Shiny input, action semantics are exposed through input$<input_id> and the latest selected dropdown item value is exposed through input$<input_id>_value. The action input increments on every selection, including repeated selection of the same item. The companion value input reflects the selected item's value, returns NULL when the selected item has no value, and preserves an explicit empty string "" when that is the selected item's value. Each committed action publishes a numeric action value. Generated from Web Awesome metadata.
