OH3 Widget "Back"

Hello Community,

I tried to build a widget that I can use to go back or to another page, depending on what I want. unfortunately it cannot be positioned exactly. Can any of you tell me what’s wrong?

Here is the code:

uid: Return
tags: []
props:
  parameters:
    - description: Name der Seite oder "Zurück"...(<u>Vorschlag:</u> <b> Zurück </b>)
      label: Name Seite
      name: prop1
      required: true
      type: TEXT
    - description: ID der Seite (<u>Vorschlag:</u> page:page_xyz </b>)
      label: ID Seite
      name: prop2
      required: true
      type: TEXT
    - description: F7-icon wählen oder leer wenn disabled (<u>Vorschlag:</u> <b> house_fill </b>)
      label: F7 icon name
      name: icon3
      required: true
      type: TEXT
    - description: Abstand von Links in Pixel (Muss nachgestelltes "px" enthalten)
      label: Abstand von Links
      name: AbLinks
      required: true
      type: TEXT
    - description: Abstand von Oben in Pixel (Muss nachgestelltes "px" enthalten)
      label: Abstand von Oben
      name: AbOben
      required: true
      type: TEXT
      advanced: false
  parameterGroups: []
