WAB - how to define featureLayer popupTemplate that will work same as the default

MichaelLev

From my (3D) custom widget in WAB Developer Edition 2.17, I need to define featureLayer popupTemplate that will display a table of the field names and field values, very much like the default popup (e.g. when I click on a feature).

The reason is that I need to "immitate" esri default popupTemplate.

I will appreciate help.

I tried:

featureLayer.popupTemplate = {
    "title": `${layerTitle}`,
    "content": featurePointed => {
        const dv = document.createElement("div");
        let num = featureLayer.fields.length;
        dv.style.height = `${num * 20}px`;
        featureLayer.fields.forEach(field => {
            let row = document.createElement('li');
            row.feature = featurePointed;
            row.textContent = `Name: ${field.name} Value: ${featurePointed.graphic.attributes[field.name]}`;
