Topic: Leaflet map using Drupal 8.7.3

bailleux free asked 4 years ago


Hello,

First of all, here is the configuration of the virtual machine:

  • Debian 9.9
  • PHP 7.3.6
  • Leaflet library 1.4.0
  • Drupal 8.7.3
  • gulp.js 4.0.2
  • Node.js 10.16.0
  • npm 6.9.0

The features of the MDBootstrap jQuery version 4.8.2 are gracefully displayed.

When implementing a leaflet-based map, the map is not fully displayed as shown in the attachment.Printscreen of the leaflet map

A similar issue (https://mdbootstrap.com/support/angular/issues-with-leaflet/) fixed by MDB staff did not help me.

In order to make sure that there is no interference coming from other Drupal modules, I created this VM with the mandatory settings to display a Leaflet map.

Please do not hesitate to ask any technical detail to solve this issue.

Best regards,

Gilles

First of all, can you tell me if any sort of error messages in the console? It would be helpful if you shared your code as well.

Hello,

Overriding line 19 of ../node_modules/mdbootstrap/scss/core/_masks.scss fixes this issue:

.view img {
    position: fixed;
}

The override is on a local scss file.

Best regards,

Gilles

Does your leaflet code without MDB files work fine? I have created an example which uses both our map and leaflet library and it seems to be working fine alongside each other, so I don't think the problem is integration between leaflet and MDB. If MDB styles are not the reason why map doesn't display correctly there is unfortunately not much I can do.

Have you considered using mdb interactive maps (https://mdbootstrap.com/docs/jquery/javascript/google-maps/) example instead? You can try to implement it and let me know if this one displays properly. I understand that without mdb code your example works as it should?

  <div id="map-container-google-2" class="z-depth-1-half map-container" style="height: 500px">
    <iframe src="https://maps.google.com/maps?q=chicago&t=&z=13&ie=UTF8&iwloc=&output=embed" frameborder="0"
      style="border:0; height: 100%; width: 100%" allowfullscreen></iframe>
  </div>

Google products are fine for me but, for some reason which is not relevant to explain here, I am being asked to use OpenStreetMap.


bailleux free answered 4 years ago


Hello Magdalena,

Thank you for asking more information.

The console does not mention any error nor warning. The debugger does not suggest anything because everything is ok. The OpenStreetMap tiles are present and their URL's are visible in the console.

But when checking the CSS tab, numerous errors show up because there are outdated properties either in Bootstrap and MD Bootstrap. There are too many errors to mention them here.

Here is the code of the div containing the Leaflet map:
