Issue template dropdown can have many entries, and it could be better to have them rendered as list later on if multi-select is enabled. so this adds an option to the issue template engine to do so. DOCS: https://gitea.com/gitea/docs/pulls/19 --- ## demo: ```yaml name: Name title: Title about: About labels: ["label1", "label2"] ref: Ref body: - type: dropdown id: id6 attributes: label: Label of dropdown (list) description: Description of dropdown multiple: true list: true options: - Option 1 of dropdown - Option 2 of dropdown - Option 3 of dropdown - Option 4 of dropdown - Option 5 of dropdown - Option 6 of dropdown - Option 7 of dropdown - Option 8 of dropdown - Option 9 of dropdown ```   --- *Sponsored by Kithara Software GmbH*
