How to align the formItems?

Question

I'm trying to create a form, but i am having issues aligning the formItems.

This is mx:Form namespace. (xmlns:mx="http://www.adobe.com/2006/mxml")

does anyone have any suggestions on how to correct this. any help would be greatly appreciated.

     <mx:VBox paddingLeft="0" height="100%">
        <form:Form width="100%"
                   textAlign="left">

            <mx:VBox>

                <mx:HBox id="snapShotSelect">

                    <form:FormItem label="My Label Here"
                                       includeInLayout="{model.formItemVisible}"
                                       visible="{model.formItemVisible}"/>

                    <mx:VBox>
                        <form:FormItem includeInLayout="{model.formItemVisible}"

Use the following code : Please adjust the width of spacer according to your alignment requirements. Also Dont miss out mentioning the width of every HBox and VBox inside the formItem. Here, I am using all mx components.

    <mx:Form>
        <mx:FormItem width="100%">
            <mx:VBox id="ContainerVBox" width="100%">
                <mx:HBox width="100%">
                    <mx:Label id="label1" text="my label here"/>
                    <mx:Spacer width="10%"/>
                    <mx:TextInput id="textInput1" text="This is text input 1"/>
                </mx:HBox>
                    <mx:TextInput id="textInput2" text="This is text input 2"/> 
            </mx:VBox>


        </mx:FormItem>

        <mx:FormItem width="100%">
            <mx:HBox width="100%">
                <mx:Label id="label1" text="my label here"/>
                <mx:Spacer width="10%"/>
                <mx:ComboBox id="myComboBox"/>
            </mx:HBox>
        </mx:FormItem>

        <mx:FormItem width="100%">
            <mx:HBox width="100%">
                <mx:RadioButton id="myRadioButton"/>
                <mx:Text text="Radio Button 1"/>
                <mx:Spacer width="10%"/>
                <mx:TextInput id="textInput3"/>
            </mx:HBox>
        </mx:FormItem>

        <mx:FormItem width="100%">
            <mx:VBox width="100%">
                <mx:HBox width="100%">
                    <mx:RadioButton id="myRadioButton"/>
                    <mx:Text text="Radio Button 2"/>
                    <mx:Spacer width="10%"/>
                    <mx:TextInput id="textInput4"/>
                </mx:HBox>
                <mx:TextInput id="textInput5" text="This is text input 5"/>     
            </mx:VBox>

        </mx:FormItem>

    </mx:Form>
</mx:VBox>
