How to customize context menu in Document Editor
Document Editor allows you to add custom option in context menu. It can be achieved by using the addCustomMenu()
method and custom action is defined using the customContextMenuSelect
Add Custom Option
The following code shows how to add custom option in context menu.
let documentEditor: DocumentEditor = new DocumentEditor({
isReadOnly: false, serviceUrl: 'https://services.syncfusion.com/js/production/api/documenteditor/'
});
documentEditor.enableAllModules();
documentEditor.appendTo('#DocumentEditor');
//Creating custom menu items
let menuItems: MenuItemModel[] = [
{
text: 'Search In Google',
id: 'search_in_google',
iconCss: 'e-icons e-de-ctnr-find'
}];
//Adding custom options
documentEditor.contextMenu.addCustomMenu(menuItems, false);
//To handle contextmenu select event
documentEditor.customContextMenuSelect = (args: CustomContentMenuEventArgs): void => {
let item: string = args.id;
let id: string = documentEditor.element.id;
switch (item) {
case id + 'search_in_google':
let searchContent: string = documentEditor.selection.text;
if (!documentEditor.selection.isEmpty && /\S/.test(searchContent)) {
window.open('http://google.com/search?q=' + searchContent);
}
break;
}
};

Document Editor allows you to customize the added custom option and also to hide/show default context menu.
Hide default context menu items
The following code shows how to hide default context menu and add custom option in context menu.
let documentEditor: DocumentEditor = new DocumentEditor({
isReadOnly: false, serviceUrl: 'https://services.syncfusion.com/js/production/api/documenteditor/'
});
documentEditor.enableAllModules();
documentEditor.appendTo('#DocumentEditor');
//Creating custom menu items
let menuItems: MenuItemModel[] = [
{
text: 'Search In Google',
id: 'search_in_google',
iconCss: 'e-icons e-de-ctnr-find'
}];
//Adding custom options
documentEditor.contextMenu.addCustomMenu(menuItems, true);
Customize added context menu items
The following code shows how to hide/show added custom option in context menu using the customContextMenuBeforeOpen
.
let documentEditor: DocumentEditor = new DocumentEditor({
isReadOnly: false, serviceUrl: 'https://services.syncfusion.com/js/production/api/documenteditor/'
});
documentEditor.enableAllModules();
documentEditor.appendTo('#DocumentEditor');
//Creating custom menu items
let menuItems: MenuItemModel[] = [
{
text: 'Search In Google',
id: 'search_in_google',
iconCss: 'e-icons e-de-ctnr-find'
}];
//Adding custom options
documentEditor.contextMenu.addCustomMenu(menuItems, false);
//To show/hide custom menu item
documentEditor.customContextMenuBeforeOpen = (args: BeforeOpenCloseCustomContentMenuEventArgs): void => {
let search: HTMLElement = document.getElementById(args.ids[0]);
search.style.display = 'none';
let searchContent: string = documentEditor.selection.text;
if ((!documentEditor.selection.isEmpty) && (/\S/.test(searchContent))) {
search.style.display = 'block';
}
};
//To handle contextmenu select event
documentEditor.customContextMenuSelect = (args: CustomContentMenuEventArgs): void => {
let item: string = args.id;
let id: string = documentEditor.element.id;
switch (item) {
case id + 'search_in_google':
let searchContent: string = documentEditor.selection.text;
if (!documentEditor.selection.isEmpty && /\S/.test(searchContent)) {
window.open('http://google.com/search?q=' + searchContent);
}
break;
}
};

let defaultCheckBoxObj: CheckBox = new CheckBox({ label: 'Hide Default Context Menu', change: contextmenuHelper });
defaultCheckBoxObj.appendTo('#default-context-menu');
let positionCheckBoxObj: CheckBox = new CheckBox({ label: 'Add Custom option at bottom', change: contextmenuHelper });
positionCheckBoxObj.appendTo('#position-context-menu');
//Initialize Document Editor component.
let documentEditor: DocumentEditor = new DocumentEditor({
isReadOnly: false, height: '370px', serviceUrl: 'https://services.syncfusion.com/js/production/api/documenteditor/'
});
//Enable all built in modules.
documentEditor.enableAllModules();
//Render Document Editor component.
documentEditor.appendTo('#DocumentEditor');
//Creating custom menu items
let menuItems: MenuItemModel[] = [
{
text: 'Search In Google',
id: 'search_in_google',
iconCss: 'e-icons e-de-ctnr-find'
}];
//Adding custom options
documentEditor.contextMenu.addCustomMenu(menuItems, false);
//To show/hide custom menu item
documentEditor.customContextMenuBeforeOpen = (args: BeforeOpenCloseCustomContentMenuEventArgs): void => {
let search: HTMLElement = document.getElementById(args.ids[0]);
search.style.display = 'none';
let searchContent: string = documentEditor.selection.text;
if ((!documentEditor.selection.isEmpty) && (/\S/.test(searchContent))) {
search.style.display = 'block';
}
};
//To handle contextmenu select event
documentEditor.customContextMenuSelect = (args: CustomContentMenuEventArgs): void => {
let item: string = args.id;
let id: string = documentEditor.element.id;
switch (item) {
case id + 'search_in_google':
let searchContent: string = documentEditor.selection.text;
