tal:attributes="name MyBooleanProperty:boolean">
<option tal:repeat="boolProp python:(True,False)" tal:content="boolProp"
tal:attributes="value boolProp; selected python:boolProp==here.getMyBooleanProperty()"/>
</select>

This block of code creates a select dropdown with two options: True and False. The select dropdown is prepopulated with the value returned by getMyBooleanProperty. The value of this form field will be stored in the attribute MyBooleanProperty?.

Add a text box type:

...
<textarea class="tablevalues" rows='5' cols="33"
tal:attributes="name MyTextProperty:text"
tal:content="here/getMyTextProperty">
</textarea>
...

This block of code creates a text box.The text box is prepopulated with the string value returned by getMyTextBoxProperty. The value of this form field will be stored in the attribute MyTextBoxProperty.

Add a text type:

...
<input class="tablevalues" type="text" size="40"
tal:attributes="value here/getMyStringProperty; name MyStringProperty"/>
...

This block of code creates a text field. The text field is prepopulated with the string value returned by getMyStringProperty. The value of this form field will be stored in the attribute MyStringProperty.

Add a select dropdown type:

...
<select class="tablevalues"
tal:attributes="name MySelectProperty">
<option tal:repeat="propOption here/getMySelectPropertyOptions"
tal:content="propOption"
tal:attributes="value propOption; selected python:propOption==getMySelectProperty()" />
</select>
...

The select dropdown is prepopulated by the value in getMySelectProperty. The value of this form field will be stored in the attribute MySelectProperty.

...
<select class="tablevalues"
tal:attributes="name MySelectProperty:int">
<option tal:repeat="propOptionTuple here/getMySelectPropertyOptionTuples"
tal:content="python:propOptionTuple[0]"
tal:attributes="value propOptionTuple[1]; selected python:propOptionTuple[1]==getMySelectProperty()" />
</select>
...

Add the form action

...
<form id='MyForm' method="post" tal:attributes="action here/absolute_url_path">

The form action should be set to a function (i.e. here/absolute_url_path) that returns the path to the object being edited.

...
<input class="tableheader" type="submit"
name="saveProperties:method" value=" Save " />
...

This submit button name will be in the format saveProperties:method. saveProperties is the method name that will be executed when the submit button is clicked.

Add the save method

...
def saveProperties(self, REQUEST=None):
	"""Save all Properties found in the REQUEST.form object. """
	for name, value in REQUEST.form.items():
		if getattr(self, name, None) != value:
			self.setProperty(name, value)

	return self.callZenScreen(REQUEST)
...

Create a saveProperty method in the effective object.
