[SalesForce] HTML5 input type number for decimals

Salesforce1 have a natural behaviour of closing picklist popup when selected. But it seems that your custom visualforce page is preventing this behaviour.

Here is the working example using opportunity "Stage" field. You can use <apex:inputfield>

<apex:form >
        <apex:outputLabel styleclass="sf1label required" value="This is a label*" />  
        <apex:inputField styleclass="sf1input" value="{!opp.AccountId}" />
        <apex:inputField styleclass="sf1input" value="{!opp.Name}" />

        <apex:inputField styleclass="sf1select" value="{!opp.StageName}" />
        <br/>
        <apex:outputLabel styleclass="sf1label required" value="Is Salesforce1?" />
        <input class="sf1input" type="checkbox"></input>
        <br/>
        <br/>
        <apex:commandbutton styleclass="sf1button" action="{!dummyAction}" value="Command Button"/>
        <br/>
        <apex:commandbutton styleclass="sf1buttonSFBlue" action="{!dummyAction}" value="Command Button Blue"/>
        <br/>
        <button class="sf1buttonSFBlue">Normal Button</button> 
    <div>
     <ol>
        <apex:repeat value="{!oppList}" var="op">
             <li class="sf1List">
               <a>
                    {!op.name}
               </a>
            </li>
         </apex:repeat>
     </ol>
    </div>
</apex:form>

I wonder if the fact that you once had advanced currency management enabled may be affecting this if you ever used it. Sometimes when you turn a feature on and use it, I believe certain internal 'flags' might get set. So even though you turn it off, there could be something internally that indicates that it was used. Again, this is all speculation on my part but it is based on a recent experience with trying to delete an approval workflow to replace it with a new one.

Even though I disabled the workflow, one user had used it to get something approved and this prevented it from being deleted. I had to delete the record that was approved, empty the recycle bin, re-create the original record, and resubmit it for approval. Just a thought.

One thing is for sure though - advanced currency management does get in the way of doing roll-ups like this. There is an Idea that you could vote up if it bothers you. It bothers me ... a lot!
