Create both horizontal and vertical menus and submenus with any amount of menus on one page. Design menus absolutely based on CSS (Cascading Style Sheets). It is possible to apply the personal CSS styles for every elements of the menu. When the submenu is bigger than the visible page area, the size of submenu will be automatically decreased. To view all the submenu you should use scrollbars.
Now let's set the html buttons web-behavior. That is, set their Link properties. To set the button link, select the button by clicking it and then enter the link address in the "Link" field on the Properties toolbox.
Another way to set the button link is to select it and then click the "Select page" button on the Properties toolbox. Open dialog will appear, in which you can select the page you would like to link to. This page's address will then appear in the "Link" field.
Also, you can assign link target attributes for each button. This will define where a linked page will be opened in your Web-browser. For example "_blank" attribute will open the linked page in new browser window. Note that link target attribute act exactly like the Target attribute of the <a> tag in HTML. To set button link target attribute, just select the button and then either choose one of the predefined values from the "Link target attributes" list on the Properties toolbox or enter your own value (window/frame name, where the linked page should be opened). Learn more about link target attributes from the user guide.
