BasemapGallery - how to limit list?

Shane_ — Fri, 14 Sep 2018 13:16:40 GMT

Using the JavaScript API 4.8, how can I create a basemap gallery with just the Imagery and Streets basemaps?

This is what I'm using to create the basemapGallery:

basemapGallery = new BasemapGallery({ view: view, container: document.createElement("div") });

Thanks,

Shane

Shane,

See this thread where I show a sample on how to remove certain basemaps.

Thanks Robert.

I tried to use basemapGallery.source.basemaps.removeAt(2);

directly after I have created the basemapGallery i.e. on the line following

basemapGallery = new BasemapGallery({ view: view, container: document.createElement("div") });

but it doesn't work. Any suggestions?

Thanks,

Shane

Shane that is why in my sample code I do not try to remove it right after I create the list.

      watchUtils.once(basemapGallery.source.basemaps,"length", function(state){
        setTimeout(function(){
          basemapGallery.source.basemaps.removeAt(2);
        }, 200);
      });

You can use `PortalBasemapsSource#filterFunction` for this purpose. Here's an example: [BasemapGallery] Filter basemaps
