If you need your current website have an admin panel which you can use anytime to manage your website contents, i can provide you a simple and high quality admin panel for that.
The admin panel i have developed and use in many web projects is easy to use and has a dynamic and tab based interface. You can switch between tabs to continue doing different tasks together.
Website admin panel can only be accessed by authorized users after user login with password. You can also have a custom configuration for admin panel access url to have a unique url for using the control panel which gives more security to keep your control panel with higher security.
In the website admin panel you can view the contents and other type of data in your web site as a grid table. You can view any record in detail, edit, delete and you can also add new rows (any type of contents) to your web site.
To edit contents of your web site, you can use the edit form that belongs to the record you want to update or an empty form to insert a new record. The edit form may have many types of fields to allow editing different types of data like text, text area, select list , date, number (float or integer), price, file upload (single or multiple), image upload (single or multiple), rich text editors etc. By using rich text editors you can also manage your page content freely in the way you want.
