# Input Type Hidden
A hidden field let web developers include data that cannot be seen or modified by users when a form is submitted.
```htmlembedded=
<input type="hidden" id="custId" name="custId" value="3487">
```
# Input Type Tel
The tel input type can be used for entering a telephone number.
```htmlembedded=
<input type="tel" id="myphone" placeholder="xx-xxxx-xxxx" required>
```
# URLs
The url input (type="url") is used for specifying a web address. Much like email, it will appear as a normal text field. On many touch screens, the onscreen keyboard displayed will be optimized for web address entry, with a forward slash (/) and a “.com” shortcut key.
```htmlembedded=
<input type="url" id="url" name="url"/>
```
# Input Type Search
The search input type can be used for creating search input fields.
```htmlembedded=
<input type="search" id="mysearch">
```
# Input Type Datetime-local
The datetime-local input type allows the user to select both local date and time, including the year, month, and day as well as the time in hours and minutes.
```htmlembedded=
<input type="datetime-local" id="mydatetime">
```
