In node red dashboard palette,dash (-) is replaced by space.How to resolve it?

In node red dashboard palette, if i want to customize the name of node suppose HTTP-response but what I see by default dash (-) is replaced by space and it always give HTTP response. I want to make it HTTP-response in the palette, so please let me know where and what to change.

#thanks

Just to clarify terminology - Dashboard is the UI generated by node-red-dashboard. You are talking about the palette in the Node-RED Editor.

I have already replied three times to this question here

The behaviour you describe is hardcoded in the Editor. There is nothing your node can do to get a - to display in its name in the palette.
