OK - problem solved... if anyone is interested, my custom tag looks
like so:
p.s. it does not yet disable the already chosen values on page load.
<def tag="select-many-custom" attrs="options, targets, param-name,
field-name, remove-label, prompt, disabled"><%
prompt ||= "Add #{this_field.titleize.singularize}"
options ||= this_field_reflection.klass.all(:conditions
=>this.conditions).select {|x| can_view?(x)}
field_name ||= 'id' #allow user to change field for
outputting values (.e.g 'user_id' )
values = this
@param_name ||= param_name_for_this
-%>
<div class="input select-many" merge-attrs>
<div style="display:none" class="item-proto">
<div class="item" param="proto-item">
<span></span>
<input type="hidden" name="#{param_name}[]" param="proto-
hidden"/>
<input type="button" class="remove-item" value="#{remove_label
|| 'Remove'}" param="proto-remove-button"/>
</div>
</div>
<div class="items">
<set param-name="¶m_name_for_this"/>
<div class="item" param="item" repeat>
<span><%= h this.to_s %></span>
<input type="hidden" name="#...@param_name}[]" value="@#{h
this.send(field_name)}" disabled="&disabled"
param="hidden"/>
<input type="button" class="remove-item" value="#{remove_label
|| 'Remove'}" disabled="&disabled"
param="remove-button"/>
</div>
</div>
<select merge-attrs="&{:disabled => disabled}">
<option value=""><prompt/></option>
<option repeat="&options.sort_by {|x| x.to_s.downcase}" value="@#
{this.id}"
merge-attrs="&{:disabled => 'true'} if (this.in?(values)
|| this.to_s.in?(values))"><%= h this.to_s %></option>
</select>
</div>
</def>
