Styles can be copied from one control to another via the Style tab. To copy a style, select the control with the desired style, and click the Copy Style button on the top menu bar.
Select the control to which you would like to copy the style, and all compatible style elements will be applied to the second control.
Common style elements can also be copied between control types. For example, in the below Zapp, both the text field and lookup field have a label. You can, therefore, copy the label's styling between the two controls.
Copying Styles to Multiple Controls
Styles can also be copied from one control to multiple controls. To do so, select the control whose style you wish to copy and click the "Copy Style" button. Hold down the Control (PC) or Command (Mac) key and a plus sign will appear next to the paintbrush cursor, indicating that you may now copy the style across multiple controls.
Continue to hold down the Control or Command key, and click each control to which you'd like to copy the style.
Copying Styles in a Group or Drill-down Page
You can also copy styles to or from drill-down pages and groups, such as Bubbles and Collapsible Groups, that require the user first to navigate into or out of them. To copy styles onto a control that is inside a drill-down page or group, select the desired control and click "Copy Style." Hold down the shift key and click into the drill-down page, Bubble, or Collapsible Group. Let go of the Command/Control key, and click the control to which you would like to copy the style.
Copying Styles Between Pages
Formatting can also be copied between entire pages. To copy a page's format, select the page and click the Copy Style button.
Then, select the page to which you would like to copy the style in the Pages menu on the left hand side of the screen.
The page formatting will then be copied.
Floating Bar styles cannot apply to Buttons outside of the Floating Bar as they are treated as different control types.
