title: HTML Input Elements for Ponzu Editor Forms

Ponzu provides a number of helpful HTML Inputs to create forms which CMS admins
use to manage content. The input functions are typically used inside a Content
type's `MarshalEditor()` func from within an `editor.Form()` - for example:

```go
// MarshalEditor writes a buffer of html to edit a Post within the CMS
// and implements editor.Editable
func (p *Post) MarshalEditor() ([]byte, error) {
    view, err := editor.Form(p,
        editor.Field{ // <- editor.Fields contain input-like funcs
            View: editor.Input("Title", p, map[string]string{ // <- makes a text input
                "label":       "Title",
                "type":        "text",
                "placeholder": "Enter the Title here",
            }),
        },
        editor.Field{
            View: editor.Richtext("Body", p, map[string]string{ // <- makes a WYSIWIG editor
                "label":       "Body",
                "placeholder": "Enter the Body here",
            }),
        },
        editor.Field{
            View: editor.Input("Author", p, map[string]string{
                "label":       "Author",
                "type":        "text",
                "placeholder": "Enter the Author here",
            }),
        },
    )

    if err != nil {
        return nil, fmt.Errorf("Failed to render Post editor view: %s", err.Error())
    }

    return view, nil
}
```
