To create a gadget with the list of datasets, click the button “Dataset List” in the empty placeholder.
In the opened dialog, select datasets which will be shown in the list. The process of dataset selection is the same as when you create a new visualization.
You can also create a list of dataset with a particular tag using the tab Select by Tags. This list will be automatically updated once new datasets with such tags appear.
If you add two tags, you will get the list of datasets with one or another tag or both.
