Editable text fields are often configured to only allow you to change the text content of the field. If a text field has been configured to also allow you to change the font or colour of the text, for example, the relevant editing tools will be visible in the top menu. The editing tools can allow you to choose the text size, font style, text colour or add other text effects, for example.
Double-click the text you wish to edit in the working area or click the icon displayed in the upper corner of the selected text. After this, select the section that you want to edit and then use the options in the top menu to apply the desired formatting. Product templates and text fields can be configured to apply selected styles or effects to the entire content of the text field or allow you to use multiple different types of formatting in a single text field.
The available editing tools depend on the product and are always configured according to the relevant style guide, which also means that some editable products will not allow you to use any editing tools. In this case, the top menu will only display the Revert, Undo and Redo commands.
