How to make tooltips permanent / always visible in leaflet

Dash Python
1

I have a dash leaflet map.

I’m creating the markers by building a dataframe (dfGeo) with columns like latitude, longitude, popup, tooltip, and icon.

Then, I create the geoJSON like this:

geoJSON['props']['data'] = dfGeo.__geo_interface__

And in the GeoJSON object definition, I point to the javascript in dashLeafletFunctions.js:

                              dl.GeoJSON(
                                  id="gisSandbox-geojson",
                                  options=dict(pointToLayer=ns("draw_marker")),
                              ),

draw_marker looks like this:

window.dashExtensions = Object.assign({}, window.dashExtensions, {
  dashExtensionssub: {
    draw_marker: function(feature, latlng) {
      var marker = feature.properties.marker_color;
      return L.marker(latlng, {
        icon: L.icon({
          iconUrl: feature.properties.icon,
          iconSize: [45, 45],
        })
      });
      }
  }
});

This works as expected.

However, under certain circumstances, I want to always show the tooltip - not just on hover.

How can I accomplish this using the pattern I’m using?

Thanks!
