I've been incorporating the MarketCluster and the associated FeatureGroup.SubGroup plug ins from Leaflet to add additional functionality to my generated QGIS2web map.

Part of my requirements is toggleable layers and where MarkerCluster works well when I had categorized layers from QGIS that were automatically clustered with separate layers this is no longer the case. To my understanding I needed either MarkerCluster.LayerSupport or FeatureGroup.SubGroup plugins to handle the additional layers and still provide clustering.

I've incorporated the CSS from MarkerCluster, JS from MarkerCluster and SubGroup, as well as called it in the map and in the respective places but the icons aren't actually clustering - image below.

The bottom 3 layers are all under the parent group mcg and all have been added to the map and called under the plugin so I'm not too sure why they are not clustering at small scales?

Var map code:

I used the blowup.js plugin as a base, and I am trying to rotate the image, and the lens to follow the rotation. But it is not working.

When I put the rotate(180deg) for example, the lens and the image are mismatched, if I remove the rotate(180deg) they are aligned.

Anybody know how to help me?

sample in JSFiddle

I have an image which is currently centered on the screen using flexbox:

I have a React application with a left-side navigation bar and then pages being rendered on the right. When I view a page on the right and scroll down then use the navigation bar to go to another page, the new page is rendered with the same scroll position as the previous page. I want the new page to always render scrolled all the way to the top.

I have done a lot of reading the last few days and everyone seems to agree that the solution is to use useEffect as follows:

I'm using the iframe-resizer package to dynamically change the size of an iframe depending on content.

However, before even trying any dynamic resizing, I run into an issue with the basic iframe: it's always 300px in width. Whatever content I place inside the iframe, the width is always 300px. Will not move; overflow is hidden if I add something >300px and still takes up 300px if my content is smaller than that.

EDIT: To be clear, My problem is that I want to dynamically change the width of an iframe (cross-domain), but it always renders at 300px and will not change. I'm using the iframe-resizer package to successfully dynamically change the height, but that's nto working on the width.

In the parent site, I'm embedding the iframe as follows:

I don't know if the title is worded correctly, but I will try my best to explain my problem. I now have a function that updates the current user's location, which works fine. The problem is that the painted pointer remains at that exact position because the decoration is painted once inside the widget and never changes.

I have looked at how google does it with the marker object, but that didn't seem to work for my app because I am not using a normal map.

Hi I know this is probably a stupid question but what does this error mean in relation to my app.js file? It didn't appear until I ran my local server. Was working fine prior.

I am using on project MUI v5.0.2. One week ago my project worked correctly (there were no errors), but today an error appeared out of nowhere (there were no changes in the code)

Error: TypeError: Cannot read properties of undefined (reading 'drawer')

The code:

I am trying to implement a offline (and yet to be added - but also a low connection) network error popup message into a clients React Native app.
