DataList is the new label for HTML5, which is used to automatically match the possible input of the form

DataList the user may enter the value, placed in the option list, when the user in the corresponding form input, according to the input keyword automatically match the contents of the option list, you can also enter the option does not exist in the value. Use the following

<input list= "Browsers" name= "browser" >//the list property of the form specifies the corresponding DataList <datalist id=
"Browsers" >   // Also DataList must be ID must be the same as the list property of the form
  <option value= "Internet Explorer" >
  <option value= "Firefox" >
  <option value= "Chrome" >
  <option value= "Opera" >

</ Datalist>

The value is displayed when we enter a keyword that matches the value of the option selected under DataList.
As shown in the following figure

If you enter a keyword that matches the option number, then each match will show

  <datalist id= "Browsers" >   //At the same time DataList must ID must be the same as the list property of the form
  <option value= "Internet Explorer" >
  <option value= "Firefox" >
  <option value= "Chrome" >
  <option value= "Opera" >
  < Option value= "FDSDD" >
  <option value= "defed" >
