When you're designing in Glide, your data is displayed on a Screen with Components on it. Components display and let your users interact with your data in powerful ways.
Some components like Collections show data from multiple rows, while others like Action Row display only a single value.
You can always see which components are visible on a screen in the Components panel on the left in the Layout Editor.
Some screens may limit you from adding new components, but most screens let you add components wherever you like.
You can edit components from the Layout Editor. Click the component you'd like to edit on the left, and configure its settings on the right.
Some components are very simple, while others are much more complex. Regardless, most components have one or more of the following areas in their settings.
Data (sometimes called 'Content' or 'Items Data') is where you configure what the component is displaying. Some components can only display a single value from your data, and others let you show multiple properties.
Design lets you tweak a component to style it how you like. With components such lists and collections, the settings can be quite extensive. But with simple components like the Text Component, the settings are minimal.
Many Components have the option to add Actions. Sometimes you can add only a single action and sometimes you can add multiple.
Most components have only two sections: The General tab and the Options tab. Most Components have only Visibility settings in the Options tab, but Collections have many other options.
When you delete Components, they don't affect the data in your table. If you accidentally delete a Component, you can hit Command Z (Mac) or Control Z (PC) to bring it back. This also works for many other steps you take as you build your app. Alternatively, you can click the Undo or Redo buttons in the bottom left of your screen.
