Inline Edit and Save not working with apex:selectlist

Question

I have a set of select options in a dropdown which the user selects and based on the option selected different sets of pageblocktables are rendered. I want them to be able to inline edit and save each of these tables. When I give these tables inline edit/save functionality without using the select list, it works perfectly. However, when I use inline editing with selectlist; after click on the save button, the page reloads but then does not show any tables and data does not get saved. I am guessing there is problem with the doSave() function in my code.

VF code:

<apex:page controller="OppsController">
<apex:form >
   <apex:panelGrid columns="2">
        <apex:selectList value="{!SectionNames}" required="True" size="1" multiselect="false">
            <apex:selectOptions value="{!SectionItems}" />
            <apex:actionSupport event="onchange" action="{!updateData}"/>   
        </apex:selectList> 

   </apex:panelGrid> 


 <apex:outputPanel >
 <apex:outputPanel id="section1" rendered="{!section1}" >
  <apex:pageBlock >
<apex:commandButton value="Save" action="{!doSaveUS}" />
      <apex:pageBlockTable value="{!OppContentUS}"  var="item" style="text-align:left;" >
             <apex:inlineEditSupport showOnEdit="SaveActiveState"  />

Answer 1

Issue with

 public List<SelectOption> getSectionItems(){
        section1 = false;
        section2 = false;

         List<SelectOption> SectionNames = new List<SelectOption>();
         SectionNames.add(new SelectOption('','-- Select --'));
         SectionNames.add(new SelectOption('USA New Business','USA New Business'));
         SectionNames.add(new SelectOption('UK New Business','UK New Business'));
         return SectionNames;

     }

Remove

section1 = false;
section2 = false;

this and add into constructor

what happend constructor always call once when page load but this getSectionItems method call everytime whenever we call a method from page
