The dropdown list web part allows an html select to be placed on the Kentico page, populated with data from either a custom table, custom query, documents in the document tree or custom options.
The dropdown list web part is highly configurable providing options for auto postback with querystring and multiple can be placed on a page; with a few macros a cascading dropdown list can be created for search or filtering repeaters or with documents it can be used to navigate to the selected page. It renders as a standard html select which makes it highly style-able. Classes and labels can be added through the web part settings.
Instructions are included in the package.
