Presenting dropdowns based on other elements

fabrikThe Cascading Dropdown allows you to limit the choices of a dropdown element, depending on the contents of another dropdown.  A common example would be a dropdown of states being dependent on a country dropdown choice.  This article goes through an example implementation. 


The cascadingdropdown plug-in is not installed by default.

  1. Start by downloading the latest version.
  2. Install the plugin, as a normal Joomla extension.
  3. Go to Extensions > Plugins.
  4. Enable the Fabrik Element - Cascading dropdown plugin.



Now you can add a new cascadingdropdown element.

  1. Go to Components > Fabrik > Elements.
  2. Click New.
  3. For Plugin, select cascadingdropdown.
  4. Select the Data tab.
  5. Choose the List, ID and Label of the source data List
  6. Select the Watch tab.
  7. Choose the element on the local list to Watch.
  8. Select the Foreign key from the source data to filter with.
