Add Querystring for all three in menu section

For mechanical submenu "GAL.aspx?GALOption=Mechanical"
For CSE submenu "GAL.aspx?GALOption=CSE"
For EEE submenu "GAL.aspx?GALOption=EEE"

Add below code in pageload

C#

if (!IsPostBack)
        {
            if (Request.QueryString["GALOption"] != null)
            {
                if (Request.QueryString["GALOption"].ToString() != "Mechanical")
                {

                    ddlCategory.Items.FindByText("Mechanical").Selected = true;
                }
                else if (Request.QueryString["GALOption"].ToString() != "CSE")
                {
                    ddlCategory.Items.FindByText("CSE").Selected = true;
                }
                else if (Request.QueryString["GALOption"].ToString() != "EEE")
                {
                    ddlCategory.Items.FindByText("EEE").Selected = true;
                }
            }
        }
