Create dynamic tree grid with expande / collapse selected rows and select checkbox for the entire row select/deselect in Salesforce lightning web component LWC | how to create tree grid with expanded/collapsed section for the entire row marked as select / deselect with checkbox in Salesforce LWC

Hey guys, today in this post we are going to learn about How to Create dynamic tree grid with expanded/collapsed selected rows and select checkbox for the entire row select/deselect in Salesforce lightning web component LWC.

A lightning-tree-grid component displays hierarchical data in a table. Its appearance resembles lightning-datatable since it implements lightning-datatable internally, with the exception that each row in the table can be expanded to reveal a nested group of items. Rows that contain nested data display a chevron icon to denote that they can be expanded or collapsed. This visual representation is useful for displaying structured data such as account hierarchy or forecasting data. To know more details about lightning-tree-grid, Click Here..
