HTML - <input type="checkbox">
The HTML input element <input type="checkbox"> is an input element to enter an array of different values. The value attribute is used to define the value submitted by the checkbox. The checked attribute is used to indicate whether this item is selected. The indeterminate attribute is used to indicate that the checkbox is in an indeterminate state (on most platforms, this draws a horizontal line across the checkbox).
Example
<label><input type="checkbox" id="cbox1" value="first_checkbox"> This is the first checkbox</label><br> <input type="checkbox" id="cbox2" value="second_checkbox"> <label for="cbox2">This is the second checkbox</label>
