B4XSearchTemplate works with a list of strings and does not support CSBuilder. You can achieve what you are looking for using B4XTable or maybe other ways. See this link for an example showing flags and search feature using B4XTable.

[B4X] B4XTable - Cross platform, sortable, searchable, customizable table

B4XTable is a paged based table. The UI is made of a horizontal xCLV. The data is stored in an in-memory SQLite database. How to use? 1. Add a B4XTable with the designer. 2. Add the columns: B4XTable1.AddColumn("US County", B4XTable1.COLUMN_TYPE_NUMBERS) B4XTable1.AddColumn("Name"...

Another good option that allows you to have a search box and display text with images is: B4X CLVTree with examples

[B4X] CLVTree - Tree View

CLVTree extends xCustomListView and turns it into a tree view: Usage: 1. Add a CustomListView with the designer. 2. Initialize CLVTree and add items: Tree.Initialize(CustomListView1) For i = 1 To 10 Dim item As CLVTreeItem = Tree.AddItem(Tree.Root, $"Item #${i}"$, Null, "")...

Also Peter SImpson suite of examples featuring xCustomListView with lazy loading and with Search capabilities is a great source to learn and apply them to real world situations. They helped me learn more about lazy loading.

✅ Part 2 Examples - Creating long lists using xCustomListView with Lazy Loading - Newer developers

Hello All, If you're not experienced with using xCustomListView (xCLV) with Lazy Loading (LL) when it comes to loading long lists of data, then I strongly suggest that you read the following post first >>>? Part 1 Basics > XcustomListView
