Hiding Custom Context Menu Items at Runtime

Question

Hello,In File Manager we are creating custom items for our toolbar and context menus.We need to hide certain items at runtime; for example, if the selected file is a video file we will show a toolbar/context menu item that is not shown for other file types or for folders.Our approach has been to create these custom items in the File Manager configuration:            toolbarSettings: {                items: ['NewFolder', 'Upload', 'SortBy', 'Refresh', 'Delete', 'Custom', ]            },            contextMenuSettings: {                file: ["Custom",  "|", "Open", "|", "Delete", "Rename", "|", "Details"],                folder: ["Open", "|", "Delete",  "Rename"],                layout: ["SortBy", "|", "NewFolder", "Upload"],                visible: true            },Then, at runtime our approach is to hide them where appropriate:            var customContextMenuOption = document.querySelector('#fileManager_cm_custom');            customContextMenuOption.style.display = 'none';            document.querySelector('#fileManager_tb_custom').style.visibility= 'hidden';This approach works for toolbar items, they are hidden or visible as expected.  It does not appear to work for context menu items, the custom item is always visible.Can you suggest what I might be doing incorrectly here?Thank You,Randy Craven

Hi Randy Craven,  
 
Greetings from Syncfusion support. 
 
We have checked your requirement with FileManager component. You can achieve your requirement by using menuOpen event of FileManager component. 
 
Refer the below code snippet. 
 




let fileObject: FileManager = new FileManager({ 
  ajaxSettings: { 
    url: hostUrl + "api/FileManager/FileOperations", 
    getImageUrl: hostUrl + "api/FileManager/GetImage", 
    uploadUrl: hostUrl + "api/FileManager/Upload", 
    downloadUrl: hostUrl + "api/FileManager/Download" 
  }, 
  view: "Details", 
  contextMenuSettings: { 
    file: ["Custom", "|", "Open", "|", "Delete", "Rename", "|", "Details"], 
    folder: ["Custom", "Open", "|", "Delete", "Rename"], 
    layout: ["Custom", "SortBy", "|", "NewFolder", "Upload"], 
    visible: true 
  }, 
  menuOpen: menuOpen 
}); 
fileObject.appendTo("#filemanager"); 
 
function menuOpen(args) { 
  if (!(args.fileDetails[0].type == ".mp4")) { 
    args.items.splice(0, 1); 
  } 
}
