### Single / Double Lines

By default, captions enter a single Essential Property text input inside your Precomp. Change the **Line 1 field** dropdown to select a different text input.

Select the **Double** button to create 2 dropdowns. This will split double-line caption text at line breaks, entering each line into two different text inputs.

{% hint style="info" %}
**Example:** Send the first line of the captions file into a text input named "Line 01" and the second line of the captions file into "Line 02".
{% endhint %}
