How to add a webpart into a special group other than miscellaneous

By default, SharePoint web parts are always put into a web part group called “Miscellaneous”.

If you want to automate this process when deploying your web parts as a Feature you can do the following:

In your web parts element manifest file

<ElementManifests>
    <ElementManifest Location=”MyWebPart\MyWebPart.xml” /> this is the file you edit
    <ElementFile Location=”MyWebPart\MyWebPart.webpart” />
  </ElementManifests>

 

Add the following elements

<Module Name=”WebParts” List=”113″ Url=”_catalogs/wp”>
      <File Path=”FlarePoint.MyWebPart.webpart” Url=”FlarePoint.MyWebPart.webpart” Type=”GhostableInLibrary”>
          <Property Name=”Group” Value=”FlarePoint Web Parts” />this is what you add for the Group
          <Property Name=”Title” Value=”FlarePoint.MyWebPart” />this is what you add for the Title
          <Property Name=”WebPartDescription” Value=”FlarePoints MyWebPart description” />this is what you add for the Description
      </File>
  </Module>

Good post on doing this via the object model
