Discussion
The context menu shown when a user right-clicks a tab in the Tabbed UI can be customized. You can change the options shown, customize the HTML displayed for the menu options, integrate language tags for multi-language support, or turn off the menu with the Tab right-click menu property.
Clicking the 
smart field button for Tab right-click menu opens the Customize Tab Right-click menu dialog. Here you can customize the menu options for the context menu or turn the menu off.
Default Context Menu
The menu definition below is the default menu generated for the tab right-click menu:
{html: 'Close',value: 1}
{html: 'Close other tabs',value: 2}
{html: 'Close tabs to the right',value: 3}
{html: 'Close all tabs', value: 4}You can insert the default menu using the Insert default menu link at the bottom of the Customize Tab Right-click menu dialog.
Customizing Menu HTML and Adding Language Support
The HTML for menu options can be customized with the html setting. Your HTML can include images. For example:
{html: '<img src="svgIcon=#alpha-icon-doc:24{ fill: #268bd2; stroke: #073642;}" > Close',value: 1}
{html: '<img src="svgIcon=#alpha-icon-docRename:24{ fill: #268bd2; stroke: #073642;}" > Close other tabs',value: 2}
{html: '<img src="svgIcon=#alpha-icon-docIn:24{ fill: #268bd2; stroke: #073642;}" > Close tabs to the right',value: 3}
{html: '<img src="svgIcon=#alpha-icon-docX:24{ fill: #268bd2; stroke: #073642;}" > Close all tabs', value: 4}
html also supports using language tags to add support for rendering your application in other languages. Both Language definition and Text dictionary tags are supported.
{html: '<a5:t>Close</a5:t>',value: 1}
{html: '<a5:t>Close other tabs</a5:t>',value: 2}
{html: '<a5:t>Close tabs to the right</a5:t>',value: 3}
{html: '<a5:t>Close all tabs</a5:t>', value: 4}Limiting Choices
You can restrict the number of options by omitting them from the list of choices. For example, if you only want to permit closing the current tab, your Tab right-click menu definition would only include one entry for Close:
{html: 'Close',value: 1}Disabling the Menu
If you want to disable the Tab right-click menu altogether, enter nomenu in the Customize Tab Right-click menu dialog.
nomenu
nomenu turns off the right-click menu.
Custom Menu Options
The Tab right-click menu does not support adding custom choices. Adding other options with values that are not 1 through 4 have the same behavior as the Close all tabs (value 4) option.
