Hello,

I don’t understand how to dynamically assign an icon to a field.

I added an icon on a field,

```xml
<field name="margin_percent" icon="red-chip" symbol="%"/>

```

1. but how to make the icon change according to the value of the field?

value \> 6, icon=green  
value \<= 6 , icon=orange  
value \<= 0, icon=red

1. Is it possible to put the icon after the value instead of in front?

The content of the attribute `icon` must be the name of a field (but it fall back to a direct icon name if the field does not exist). So this field should contain the name of the icon to display. So usually it is a `Function` fields which a `on_change_with` method as `getter` so it can change the value dynamically.

Yes for that you must use a `suffix` tag inside the `field` tag, see [Views — Tryton server](https://docs.tryton.org/projects/server/en/latest/topics/views/index.html#prefix-suffix)
