Lizmap-web-client: Form filtering working on more layer at the same time?

Is your feature request related to a problem? Please describe

Describe the solution you'd like

Hi, currently form filter can work only on one layer at a time and it’s been a great improvement.
Do you think it's feasible to add the option of filtering two or more layers at the same time? Would it be easy or it's a high time-consuming activity?

Describe alternatives you've considered

Additional context

We are also testing a change in the user interface. We have modified the UI as shown in the image below; if you are interested, we could share the js code with you. We think it’s better for users to see the TOC and filter at the same time.

Hi @tethysgeco . Can you share the js code here with your modifications?

hi @ygorigor, we're trying adding these lines in media/js:

// add some custom style
var style = ""
$( style ).appendTo( "head" )

lizMap.events.on({
'uicreated': function(e) {
setTimeout(() => {

        // add filter panel title
        $("#filter #filter-container").before('<h3 style="margin-bottom: 40px; border-bottom: 1px solid rgba(255,255,255,0.5);"><span class="title"><span class="icon" style="background-image: url(/css/filter-icon-white.png); background-position: center; width: 20px; background-size: contain; height: width: 20px; height: 20px; display: inline-block;"></span>&nbsp;<span class="text">Filter</span></span></h3>')

        // add filter button on layers panel
        $('#switcher-layers-actions').append('<button class="btn-custom" id="custom-filter-switcher" style="outline: none;background: rgba(255,255,255,0.9); border-radius: 3px;color: black; margin: 8px; margin-right: 0px;">Filtra dati</button>');

        // open filter panel on click
        $("#custom-filter-switcher").click(function(e) {
            e.preventDefault();
            setTimeout( function() {
                $("#filter").toggleClass("active");
            }, 200);
        })

    }, 800);   
}

});

it definitely can be improved..

As one filter is reset when choosing another layer (in the filter GUI) I would say that this is a bug rather than a feature request. Opinions? @rldhont

@mdouchin is it a bug or a feature request ?

This line can be commented out to get desired behavior but I've not tested for undesirable side effects.

It requires a big refactoring of the code responsible for applying filtering. At the time present, it is not possible to apply a filter on more than one layer.

Keep in mind that triggering a filter applies also the filter to the child layers by following QGIS relations defined in the project, so it is not an easy stuff to change, and changing only the UI won't be enough
