            QUESTION

            How to assign multiple inputs and outputs to app.callback with hover_feature or click_feature in dash-leaflet?
            Asked 2021-Nov-20 at 17:56

            I'm having trouble getting multiple inputs and outputs to work in Dash-leaflet. Essentially, I want to do the following: on a mouse click place a marker on the map, and when hovering over a country highlight an area of the map with a polygon and display some information about the country being hovered over in a different pane. I implemented each of those functions in a separate app.callback, as in the below code.

            I found out how to do this, I had to add another dl.LayerGroup to the dl.Map object with a different id, then assigned each function to output to a different layer.

            How can I make an interactive world map in dash-leaflet?
            Asked 2021-Nov-07 at 21:36

            I'm trying to replicate this example from the dash-leaflet documentation, but for world countries instead of US states. However, when I run the code from the documentation on my machine I don't see the blue state borders in the output visual.

            I figured this was because I don't have the right geojson data locally, so I downloaded some country border GeoJSON data from here but it's unclear to me how to get the dl.GeoJSON function to make use of that data. How can I get country borders to show up on the world map in the same way the states do in the linked example?

            Mapping dash-leaflet controls to other buttons outside the map
            Asked 2021-Jul-25 at 11:35

            Dash-leaflet allows adding controls, such as ZoomControl, MeasureControl, or EditControl to map layers. I was wondering if it is possible to use Dash buttons to perform the same actions as these controls.

            For example, is it possible to zoom in/out using a couple of Dash buttons placed outside the map?

            To use Dash buttons, you would need to create callbacks that perform the desired modifications of the map properties. Here is a small example where Dash buttons mimic the behavior of the ZoomControl,

            While it is possible to filter the data in Python, it can introduce significant network overhead depending on the data size (the data is transferred from the server to the client each time the filter changes). If you do the filtering client side, you only have to transfer the data once, i.e. the performance difference can be dramatic.

            The client side filtering can be implemented by adding a JavaScript asset (i.e. a .js file placed in the assets folder) with the filtering function as per the documentation,
