Shape with a text

Can we have a text inside the shapes which will be in the symbol palette. So that the user can directly drag the shape along with the text

If this is possible please share the sample code

Hi SaiSravya, 
 
To display text to shapes in symbol palette, please use the description property in the getSymbolInfo function as shown in the below code example. 
 
Code example: 
      <ejs-symbolpalette id="symbolpalette" [palettes]='palettes' width="100%" height="200px" [getSymbolInfo]="getSymbolInfo" [symbolHeight]=80 [symbolWidth]=120> 
            </ejs-symbolpalette> 
 
public getSymbolInfo(symbol: NodeModel): SymbolInfo {   
  // display text for palette item 
    return { description: { text: symbol.id }, fit: true }; 
} 
 
 
Regards, 
Shyam G

Hi SaiSravya, 

By analyzing your screenshot, we found that OpenNew.css file is not referred properly. Please remove that file from your sample which is not necessary for our diagram control. However, we have created an angular sample locally with your code example and it is available at the below link for download.
