Working with Components
To place new components to the Web Application just drag the desired component from the upper panel and drop it into the place you want this component to be rendered. Every component has a popup with applicable settings. Usually, this popup can be opened by clicking the settings icon or component itself.
Some components like tables, views, forms need to have data sources. E.g. to fill a table with data, you need to specify endpoint as the data source. Table columns will be automatically populated with selected endpoint variables and you can adjust them the way you want - from title to rendering options.
Almost every Web Application component needs to have a data source (linked endpoint). All fields for form and view, columns for the table are taken from the linked endpoint.
