Controls allow you to take your Coda doc to the next level. With Controls, you can add interactive elements to your documents that are typically reserved for applications - for example, you could add a checkbox column and then conditionally format based on that.
How to add a Control
To add a Control to an existing Table, click the 'T' icon at the top of any new column. Then scroll down to select a Control type. You can select from the following Control types: Select List, Checkbox, or Slider.
Filtering Tables and Views based on Controls
You can filter a table or view by the control's value using the Matches function. This makes it easy to match not just on exact values, but also for lists and ranges.
Simply click the filter icon to apply your formula of choice to your table.
Pro Tip: You can filter any of your tables and views based on any Control in your doc. There's no need to have it in the same section - pretty handy!
