There are two ways to add apps to your database Toolbar, which lets you run apps by selecting them from a dropdown.
To add an app that appears in the toolbar dropdown whenever a row is NOT selected:
Now that app should be an option in your toolbar dropdown.
Follow the steps below to add an app that appears in the toolbar dropdown whenever one or more rows are selected.
In order for your App to use data from your database, you must add that database as a Data Source:
Whenever you add a Data Source to your app, you must provide a mechanism for the end-user to "look up" a specific row within your Data Source table. Adding the app to your database Toolbar is such a mechanism (the end-user, i.e. you, will be able to "look up" a row by clicking on it directly from within the database).
As a result of adding the app to your database Toolbar, you have access to variables for each column in your database table. Use these variables to create a document template.
As long as your app is activated, it will appear on your database Toolbar.
You can now select a row of data, then select the app you want to use that data in. You can even select multiple rows at once.
