I created a mapbox map with markers based on the latitude and longitude in my database.
now I need to insert on my mapbox map, when I click on a marker, a popup that is not above the marker but lateral, outside the map. I need that when I click on a marker on the map, I open a side panel in which to insert various information.
I have tried with this: https://docs.mapbox.com/mapbox.js/example/v1.0.0/marker-tooltips-outside-map/ but I don't know if it is ok.
how can I do?
this is my code
<?php
$connection = mysqli_connect("localhost","root","","mytable") or die("Error " . mysqli_error($connection));
$sql = "select * from mytable";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
$geojson = array(
'type' => 'FeatureCollection',
'features' => array()
);
while ($row =mysqli_fetch_assoc($result)) {
$properties = $row;
$feature = array(
'type' => 'Feature',
'geometry' => array(
'type' => 'Point',
'coordinates' => array(
$row['longitude'],
$row['latitude']
)
),
'properties' => $properties
);
array_push($geojson['features'], $feature);
}
?>

Let's say I'm a purple polyline and am using a purple icon for markers with one layer but wanted to use orange polylines and orange marker icon's for another layer. How would I do that? Is there an onlayerchange event? But even if there were how could I change all the icon's for all the markers? Alternatively, maybe I could delete all the markers and then replace them, albeit with a different icon, but idk how to delete markers, en masse or otherwise.
Any ideas?
I am not sure if I understood correctly but here is what you can do.
If you want to toggle between markers with polylines and assign different color you can use this plugin and return icon markers by passing the color.
const icon = (color) => L.icon({
iconSize: [25, 41],
iconAnchor: [10, 41],
popupAnchor: [2, -40],
iconUrl: `https://raw.githubusercontent.com/pointhi/leaflet-color-markers/master/img/marker-icon-2x-${color}.png`,
shadowUrl: "https://unpkg.com/leaflet#1.6/dist/images/marker-shadow.png"
});
and then you have the latlngs and assing to the markers an icon with the prefered color
var places1 = [
{ latlng: [39.61, -105.02], popup: 'This is Littleton, CO.'},
{ latlng: [39.74, -104.99], popup: 'This is Denver, CO.'},
{latlng: [39.73, -104.8], popup: 'This is Aurora, CO.'}
];
places1.forEach(place => L.marker(place.latlng, {
icon: icon('violet')
}).bindPopup(place.popup).addTo(cities1))
and here define the polyline color
L.polyline(places1.map(({latlng}) => latlng), {
color: 'purple'
}).addTo(cities1);
Similarly you can follow the same steps for any other overlay

For the scenario you want to change the color upon baselayer change:
you can still reuse icon() function and use now the follow chunk to change the color dynamically when the layer is changed by listening to map's baselayerchange event
function addMarkersAndPolyline(color) {
places.forEach(place => L.marker(place.latlng, {
icon: icon(color)
}).bindPopup(place.popup).addTo(cities))
L.polyline(places.map(({
latlng
}) => latlng), {
color
}).addTo(cities);
}

In https://leafletjs.com/examples/layers-control/example.html there are two layers - Grayscale and Streets. It defaults to Grayscale but how would one change the default to Streets instead?
In that example there's this:
var map = L.map('map', {
center: [39.73, -104.99],
zoom: 10,
layers: [grayscale, cities]
});
I tried swapping the order of the variables in layers but that didn't do anything.
There's also this:
var baseLayers = {
"Grayscale": grayscale,
"Streets": streets
};
I tried reversing that, as well, without success.
I even tried renaming the names of the layers, thinking that it might be done alphabetically, but no such luck.
Any ideas?
It has to do with which layer has been added to the map. So remove the array layers from the map instance and add streets layer to the map. That will define the preselected layer.

What am I doing wrong? The intent is to have a few (say 6) leafletjs panes, each containing many markers and polylines, so the panes can be hidden independently. Here is a simplified program showing just two lines and markers in jsfiddle. The problem is, the polylines all get grouped in the same SVG and all get hidden together. Each pane in the example should show one polyline and one marker.
I don't want to remove the polylines from the map to hide them, then recreating them would not perform well.
If needed, the polylines could be drawn using D3 on top of the leaflet map but I was hoping it could all be done in leaflet.
Thanks!

I've got mapbox separate geocoder two autocomplete inputs with output CSS visual crossing problem - when I input something, class .suggestions-wrapper goes underneath the second input (input.mapboxgl-ctrl-geocoder--input) is there any way to make it work properly?

There is two ways to resolve this problem for now:
1) change CSS style for 1st field so the .suggestions class with all the addresses go under the 2nd field;
#pick_up_forntinput ul.suggestions {
top: 60px;
position: absolute;
}
2) making the script for 2nd field so it will disappear on .suggestions class appear

when you mouse over a cluster, Leaflet.markercluster should show the bounds of its markers. this is the (simplified) code I am using:
map = new L.Map('map');
L.tileLayer(
'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
maxZoom: 13,
attribution: 'Map data © OpenStreetMap contributors'
}
).addTo(map);
map.setView([51.505, -0.09], 11);
let deflate_features = L.deflate({
minSize: 40,
markerCluster: true
});
deflate_features.addTo(map);
var polygon = L.polygon([
[51.509, -0.08],
[51.503, -0.06],
[51.51, -0.047]
]);
deflate_features.addLayer(polygon);
var polyline = L.polyline([
[51.52, -0.05],
[51.53, -0.10],
], {
color: 'red'
});
deflate_features.addLayer(polyline);
#map {position: absolute; top: 0; bottom: 0; left: 0; right: 0;}

why does the cluster coverage on hover not show?
coverage is not shown if there are only 2 objects... :|
adding a third object, e.g.:
var polyline2 = L.polyline([
[51.535, -0.1],
[51.525, -0.05],
], {
color: 'green'
});
deflate_features.addLayer(polyline2);
enables cluster coverage:
