Easy Menu provides two JavaScript functions that can be used to hide or show hidden menu items at client side:

HideItem - has the following syntax:
ob_em_EasyMenuID.HideItem(id)
     · id - The id of the item to hide.

ShowItem - method has the following syntax:
ob_em_EasyMenuID.ShowItem(id)
     · id - The id of the item to show.

Note:
     - EasyMenuID is the id of the Easy Menu to which we want to hide/show the item.
     - document.getElementById("EasyMenuID").object is the same as ob_em_EasyMenuID.



Test hiding and showing items to the menu on the right (make sure you enter unique IDs):

Id:   Id:

Item 1 - id=item1   Item 2 - id=item2   Item 3 - id=item3   Item 4 - id=item4   Item 5 - id=item5

Here is the code for the buttons:
<input type="button" value="Hide Item"
     onclick="ob_em_EasyMenu1.HideItem(document.getElementById('hide_itemId').value);">
<input type="button" value="Show Item"
     onclick="ob_em_EasyMenu1.ShowItem(document.getElementById('show_itemId').value);">
