Sisyphus is a JavaScript library for automatic local data storage for forms, lists, etc.

Sisyphus as a mythical figure is quite tragic, but this library would help a lot if it were implemented in every forum and app where writing long text is imperative.

Once the form (or checkbox) has been submitted, the data is removed so it won’t stay there for eternity.

A concern about data safety raises immediately, but, as HTML5′s data storage is rather safe, it should be at least somewhat safe for visitors to save data in the local storage.

eComboBox is a jQuery plugin for creating editable boxes. These “Combo boxes” are useful for tagging, sorting data, forms, and more.

This simple code will generate a Combo Box:

  $("#cb").eComboBox();

 <select id="cb">
      <option>value 1</option>
      <option>value 2</option>
      <option>value 3</option>
 </select>

Combo Boxes can be customized: prevent users from editing them; prevent users from adding new entries — and vice versa.

eComboBox is an immensely useful plugin for creating easy-to-use backends, tagging (much like the tagedit plugin), and so on.

Formly is a jQuery plugin for managing forms. It’s rather impressive in comparison to the existing form making/validating frameworks.

What’s so impressive about Formly is that it fetches the existing elements of a form and makes it really easy to style it with CSS and maybe a touch of jQuery goodness.

By default, Formly can validate email addresses and website addresses, and also required fields.

Formly is an easy-to-use solution for styling and validating forms.

Ideal Forms is a small yet powerful framework for making forms.

Ideal Forms make styling forms a pinch easier, plus it’s almost hideously easy to use.

The coder can insert a number of preset variables into form, for example, you can insert labels, buttons, select menus, etc with very minimal code.

Then again, one can question whether or not making a form requires a framework.
