-The Symbol Palette [`nodeTemplate`](https://help.syncfusion.com/cr/aspnetcore-js2/Syncfusion.EJ2.Diagrams.SymbolPalette.html#Syncfusion_EJ2_Diagrams_SymbolPalette_NodeTemplate property allows you to define reusable HTML or SVG structures that can be applied to multiple symbols. This approach is efficient when several palette symbols share a similar visual structure but contain different data.
-
-Templates should be created within `<script>` tags using unique IDs, which are then assigned to the symbol palette `nodeTemplate` property. When symbols are dragged from the palette, the diagram automatically applies the corresponding template and binds the symbol's data to the template elements.
