My question is similar to leaflet-draw delete button remove "clear all" action but I want to remove save option instead of clear all.
Well, there are no customization provided by draw api to do that. So I have added a custom css to hide it.
Apart from that, we can also customized the plugin as follows :
To change the text :
L.drawLocal.edit.toolbar.actions.clearAll.text = t('Clear');
To overwrite the clear method :
L.EditToolbar.Delete.prototype._enableLayerDelete = function(t) {
me.drawToolbar = this;
(t.layer || t.target || t).on("click", me.clearAllCustom, this)
};
