How to set Parameter as a List

You might also be able to use Get Data From URL parameter and set the data type of the Parameter to the type of custom data you created in your app only if you are sending the unique ID of each item in the URL parameter (Bubble automatically detects the entry when you specify the data type in the Get data from URL expression, so no need to do a search)…this definitely works for a single item, but not sure if it will also work for a list of items.

Test it out by putting a text element on the page, and a dynamic expression for Get Data from URL parameter to see how Bubble URL decodes the list of parameters (does it come back with a delimiter of a comma or does it use the URL coded value)…if it URL decodes and separates the values with a comma, then you can do Get data from URL parameter, set the type and then use the split by operator with the split being a comma…Bubble should be able to recognize each item without a search (again only if you are using the unique IDs)…if you are using anything other than the unique IDs then the above link will help.
