I am trying to have a TMP Input Field with multiline (wrapped) placeholder. The input field has its content type set to Integer Number. Placeholder text has some string as text and has wrapping set to "enabled". In prefab editor, it looks ok (text is wrapped). However, when the scene loads, placeholder text immediately has its wrapping reset to "disabled".

The problem: I assume Input field resets the wrapping to disabled on child text, because its content is not multiline, as specified here. I can't set the input field to accept multiline - the option is not in inspector; I can see it if I switch to Debug mode, but as soon as I set it to multiline it switches back to single line. So, how do I set the wrapping on placeholder to enabled without it getting switched back to disabled in runtime? Or, alternatively, how do I set my InputFiled to be multiline (I assume that will fix the wrapping on the placeholder)?

What I have for now: I have an input field that works like this: when it's not focused, there is a multiline text, for example: "Write your\nnumber here!". When focused, it's replaced by empty line and user can enter an integer number. On finishing input (OnEndEdit) I use the input to spawn some GameObjects and then replace the text again with "Write your\nnumber here!". Editor screenshot: screenshot

Right now it works as I expect. However, now I want to dynamically change the placeholder text, so I don't know where the newline will be and I would like for TMP to wrap the text for me, same as it does in Text component with Wrapping enabled.

So: how do I use TMP's wrapping - enabled on InputField without it getting reset to disabled? Either both the user input and placeholder, or just on placeholder itself - doesn't matter.

MultiLine is only available if the Content Type is set to Standard or Auto Corrected.

As soon as you set the input type to Integer Number it basically behaves just like an integer field in the Unity Inspector: No line wrapping but rather overfloating and scrolling to the right.

Alternatively if you need multi lines you could set the Content Type to Custom and then fully flexible adjust it to your needs like e.g.

  • LineType : Multi Line Newline
  • Line Limit: 0
  • Input Type: Standard
  • Keyboard Type: Default
  • Character Validation: Integer

And in general: Of course you also can't set a text to an input field that only accepts integer numbers ;) Rather set your placeholder text in the Placeholder object!

Anything that is applied to the Placeholder will be displayed automatically as long as there is no value typed in the input field!

  • Thank you, setting content type to custom was exactly what I needed to do! However, just for clarity, on the second point: as I described in the question, the first way (setting the text through OnEndEdit) works perfectly well, so you definitely can set text to a field that accepts integer numbers even without any placeholders. The Content Type field is used for verifying user input, basically a filter for what user can and can't put there and what screen keyboard type appears. It doesn't verify what you put there with SetTextWithoutNotify or just with manipulating child TextMeshPro =) – defaultUsernameN Nov 25 '21 at 13:35
  • @defaultUsernameN Yeah I know you *can* do this ... but you really don't **want** to do this ;) You can just make the text empty so the placeholder is displayed again – derHugo Nov 25 '21 at 13:41
