# Feature: #99285 - Add Fluid TrimViewHelper {#feature-99285-1670321970}

See [forge#99285](https://forge.typo3.org/issues/99285)

## Description {#description}

A trim ViewHelper to trim strings is now available.

Possible sides are:

-   `both` Strip whitespace (or other characters) from the beginning and end of a string
-   `left` Strip whitespace (or other characters) from the beginning of a string
-   `right` Strip whitespace (or other characters) from the end of a string

### Examples {#examples}

#### Trim from both sides {#trim-from-both-sides}

```html
#<f:format.trim>   String to be trimmed.   </f:format.trim>#
```

Results in the output:

```text
#String to be trimmed.#
```

#### Trim only one side {#trim-only-one-side}

```html
#<f:format.trim side="right">   String to be trimmed.   </f:format.trim>#
```

Results in the output:

```text
#   String to be trimmed.#
```

#### Trim special characters {#trim-special-characters}

```html
#<f:format.trim characters=" St.">   String to be trimmed.   </f:format.trim>#
```

Results in the output:
