Once you’ve uploaded your customized theme, you can use it for every form in an application or for specific forms. To use your theme in every form in an application, click Applications from Live Forms’s left-hand menu. Click the properties icon underneath your application’s name. When the Properties page is displayed, click the Choose Theme dropdown box and select your customized theme.
This will apply your new theme to any new forms you create, but it won’t automatically change the theme for existing forms. To update an existing form with your new theme, locate the desired form and click Edit. Click the toolbar at the top of the form to access the form properties on the left side of the Forms Designer. Click the Style tab, and pick your customized theme from the Theme dropdown box.
The theme can be selected dynamically via the form Url parameter _themeId. This parameter takes precedence over the theme selected at either the Application or in the Form itself as shown above. _themeId can be set to either than name of the theme, "Professional Green" in the case above. Or it can be set to the unique theme Id. You can find the Id via Copy Link Location on the Edit button or theme name in the Themes tab.
