Recent Questions Menu Treeview Con Checkbox
Q: The button menu is on the top of the screen but it has lines through each of the menus just after the words and before the arrow on each of them.
I have stretched the menu out tocover the whole of the top of the page but i need to get these lines out of the menu.
Can you please help me with this problem
A: See images in Vista Templates have the fixed width and height (92 x21):
var itemStyles = [
["itemWidth=92px","itemHeight=21px","itemBackColor=transparent,transparent","itemBorderWidth=0",
"fontStyle=normal 11px Tahoma","fontColor=#3A3A3A,#000000","itemBackImage=data-vista-2-04.files/btn_olive.gif,data-vista-2-04.files/btn_white.gif"],
];
When items text is too long you can have such effect.
You can try to use combined background for your items, for example:
var beforeItemImage = [,]; //left-side image for normal and mouse over state
var itemBackImage = [,]; //background or image for normal and mouse over state
var afterItemImage = [,]; //right-side image for normal and mouse over state
var beforeItemImageW = '';
var afterItemImageW = '';
var beforeItemImageH = '';
var afterItemImageH ='';
But you should create a small images in any Graph Editor, for example:
button_n_back.gif
button_n_left.gif
button_n_right.gif
button_o_back.gif
button_o_left.gif
button_o_right.gif
Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Javascript/DHTML Tree such as in JavaScript Tree Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Javascript/DHTML Tree into the <table> or <div>.
Q: I'm still having the issue with the sub-menus not being in the proper place, however I was able to fix the issue with menu now showing up in IE at all, it turns out I forgot a tag. So do you know why the sub-menu alignment changes depending on the browser window size? Either of the links below should give an example.
A: See, the problem is that the script can't get css properties of the object if they are described in separate .css block (or file).
In other words, you can't get the value of "position" attribute of the object if the object doesn't have this property within inline style(style="position:absolute"). To get the value you should move .css style into style="" attribute.
Please, try to add your
css file -> inline css, for example:
You should add style="position:absolute;"
to the
<DIV id=navholder>
So, you'll have:
<DIV id=navholder style="position:absolute;">
Q: There is a grey line that surrounds my menu (its on a page with black background. How do I get rid of the grey line?
A: See, you set the shadow for the top items and submenus
var shadowLen=2;
var shadowColor="#C4C4C4";
var shadowTop=1;
You should set
var shadowLen=0;
var shadowColor="#C4C4C4";
var shadowTop=0;
