Show active layer preset

Our team has built a workflow to list the presets as a drop down for this that also can have a default set or take a querystring parameter to set at load.

If interested, we can supply the workflow.

i would be very interested in this. I've been working on the querystring parameter from a url for a while with limited success.

Hopefully this works

You can add a querystring parameter
preset=presetname

NOTE: Just know this parameter can't be tested from the Web designer for some reason…..really doesn't like querystring parameters - maybe there is a way, just not aware of it.

Example of the parameters:
NOTE: leave “item:” off the preset value (this is the preset object path). If you send it in it with item: it won't be accessible….we add it on in the workflow later when setting the preset.

{
    "presets": [
        {
            "name": "Aerial Photo Locator",
            "value": "//layer-preset/36a9c691-b403-43d1-a9a3-9dd6a92e2fdd",
            "default": "true"
        },
        {
            "name": "Document Retrieval",
            "value": "//layer-preset/2c099530-0ec7-425b-ac0e-2519d6cb26a8"
        },
        {
            "name": "Parks",
            "value": "//layer-preset/c5a8f4a5-e52b-4097-802f-1a287fbaaa5e"
        }
    ]
}

We just added a Workflow item into the Layers Row above the Layers List

And set Layer Presets visibility to Hidden
