Connecting the Dropdown to your Table

Pulse allows creating interactive dashboards, a user can either push a button, select a dropdown, click a chart or table that then displays a customized resulting table or chart. Pulse enables this interaction by using variables.
When a user clicks a Dropdown, a variable is populated.
If that variable is referenced in an SQL query, the query is ran and the result updated.

To connect our dropdown select to the table query:

  1. Check the key name of the dropdown in the form. In the screenshot below it is called key1
  2. Change the table query to be -1000 sublist select from trade where sym =`${{key1}}.
  3. Select a dropdown entry and watch the table update.
